' l This inventionrelates to burners for burning gas for heating purposes, 'ai'id'theburncr is designed tobe used in any situation where i it is desired to use either natural or artificial gas as a heating agency. i

The general object of the present invention is to provide a burner which will operate with very low pressure gas.

A further obj ect is to so construct the burner that it will secure a thorough admixture of the gas with air and thus burn the gas very economically and at the same time secure a hot blue flame.

A still further object is to providemeans' whereby air may be drawn into the mixing tube and the gas thoroughly mixed with the air before and at its point of combustion.

My invention is illustrated in the accompanying drawing, wherein Figurel is a top plan view of my improved burner;

Figure 2 is a side elevation thereof; Figure 3 is a longitudinal section thereof. Referring to this drawing, 10 designates a tube of any desired length and of any desired metal, which tube at one end is provided with p a screw-threaded nipple 11 and a nut 12; Disposed within the nipple 11 and projecting into the tube 10 is a gas jet 18 having a relatively small bore 14, this bore not being coaxial with the axis of the tube 10 but being directed downward and forward so that the jet of gas escaping from the bore strikes the bottom of thetube 10 adjacent the forward end of the tube. This tube 10 on each side of the gas burner tip or nozzle 13 is cut away so as to provide two openings 15, and it will be noted that the tube 10 does not touch the projecting end of the tip but is spaced above 40 and below the tip. Thus plenty of air can enter the tube 10 and immediately around the tip and in advance thereof.

In advance of the opening 15 the top of the burner is formed with an air inlet opening 16.

This opening is formed by cutting straight downward through the tube at the forward end of the opening and cutting downward and forward and intersecting with the vertical cut from the rear portion of the tube;

:30 Thus in side elevation the opening is triangular in form. The downwardly and forwardly extending wall 17 of the opening is approximately parallel to the direction of the jet of gas issuing from the bore .14 of the tip that the gas strikes the bottom of the tube 10 13 sov in advance of theopenin'g 16 and approxi- 'matelyin line with the inclined wall17,

The forward end ofthe tube 10 isformed with the upwardly and forwardly'extended 1 and longitudinally rounded deflector '18 may be made integral with the tube and formed by splitting the end ofthe tube and then flattening which the tube laterally, the lower corners of adjacent the tubeso as to form the wings 19.

Preferably this deflectoris provided with a "NE-HALF To, SOLOMON the deflector being turned over upon the lower end of the deflector and In the use of this invention, the jet of gas projected from the tip 13 strikesthe bottom of the tube or pipe 10 and then rebounds upward. This jet of gas draws air into the tube 10 at the openings 15 and at the openings'lfi and the rebounding of the jet as it strikes rfirst upon the bottom of the tube 10, then upon the topthereof 'where it is deflected downward toward the base of the deflector l8, and then the deflection of the mixed air and gas upward, tends to thoroughly mix air with the gas so that in actual practice a perfectly blue flame is discharged upwa-rdand outward from the base of the deflector, this blue flame being fan-shaped and giving an intense heat. The openings 20 permit the introduction of air into the flame itself so that a thorough intermingling of the air is secured with the gas and the effect is as if the gas was forced outward under steam presburner and it may be used anywherewhere natural or artificial gas is to be'used for heating purposes. It will not backfire and may be used for boilers, hot air furnaces, ranges and in other places of like character. Iclaim:-' W 1. A gas burner of the character described comprising a tube, a gas jet entering one end of the tube and having its axis disposed at an acute angle to the axis of the tube whereby the gas discharged from the jet impinges at a place against the wall of the tube, air openings disposed rearward of said place where the gas jet strikes, and a deflector disposed angularly with respect to the tube and against which the intermingled jet of gas and air strikes, the deflector adjacent the tube being formed with inwardly turned wings defining air openings.
